I'm quite a newbe in the field of motives & A1 homotopy theory, so please forgive me if the question is too elementary: In the intro from [wikipedia on Nisnevish topology][1] is remarked that it's founder Yevsey Nisnevich was originally motivated by the theory of adeles. Could somebody elaborate which features/ nuances in the development of Nisnevich topology reflect the striking influence on it by the theory of adeles as stated there?
